Image fits files for Rapid-response radio observations of short GRB 181123B with the Australia Telescope Compact Array

Australia Telescope Compact Array (ATCA) fits Stokes I images of gamma-ray burst (GRB) 181123B. These fits images are from data obtained using the ATCA rapid-response system and began 12.6 hours following the Neil Gehrels Swift Observatory detection of GRB 181123B. The observations were taken at 5.5 and 9 GHz, integrating for 8.3 hours. No radio emission was detected in these data from this GRB. Two Stokes I fits images have been uploaded for each frequency. The files GRB181123B_5GHz_pbcorr.fits and GRB 181123B_9GHz_pbcorr.fits are the primary beam corrected images of the field of GRB 181123B at 5.5 and 9 GHz, respectively. The files GRB181123B_5GHz_sub_pbcorr.fits and GRB 181123B_9GHz_sub_pbcorr.fits are primary beam images of the same field but for which the clean model of all field sources was first subtracted from the visibilities.
